    Sounds like you are using a progressive machine. That might add to the difficulty in finding the real problem by going step by step through the process. Size one of the swollen cases if you decide you want to take a chance on using them and see if they chamber. Then go on to the deprime and flare step, then seat, and then Crimp.

    If the full length sized case does not easily chamber, resolve that issue before the next step.

    I'm looking through the "once-fired" brass that I bought, and a bunch of them look like this.

    These are cases that I have NOT fired through my gun or with my loads.


    I screwed my sizing die down further (now it touches the shellplate) and backed off the crimp die 1/6th of a turn, and the problem seems to be reduced... The real test will be whether they chamber easily.
    No need to wait to shoot them to find out. Any time there is a fit problem (or bulge) measure. Measure the cartridge OD along the body, from neck to head, in a few places...
